LOCK.

To all whom t may concern.'

Be it known that I, ALEXANDER BLOCK, a citizen of the United States, and a resident of the city of New York, in the county and State of NewYork, have invented certain new and useful Improvements in Locks, of which the following is a specification.

rlhis invention relates to locks, and particularly to locks that may be used upon swinging or sliding` doors for securely locking either of said types of doors. The principal object of my inventon is to provide a bolt that shall lockthe door when shifted from the casing into the keeper, and sub-v sequently to the locking operation, to move in a direction for interlocking the casing with the keeper. ln a lock of this type the chances of its being picked or jimmied or the bolt otherwise displaced or dislocated by a burglar reaching thereto with a jimmy through the exterior of the door, are'reduced to a. minimum.

rhe present invention is an improvement upon the lock disclosed in my application filed January 2nd 1920, Serial No, 348,902. It differs from the latter in replacing the cam for swinging' the bolt into engaging position, with a carrier for moving the bolt into such position, in a direction vertical to the `locking and unlocking movement of said bolt. In the present invention the bolt is adapted to move into and out of locking position with the ystuds on the carrier acting as guides, to be subsequently actuated by both studs, through said carrier, and not as in the device filed January 2nd, wherein one of the studs actuates the bolt and the other acts as a pivot therefor.

Other objects and advantages will appear in the specification given herein. i i

In the accompanying drawings, Figure 1` is la sectional elevation of the lock showing the disposition ofthe mechanism when in unlocked state. Figure 2 is a view similar to that shown in Figure 1, but showing the arrangements ofthe parts of the lock'when in locked and interlocked state. Figure 3 is a crossfsection of the lock along a line .Pi- A.. Figure 4- is a longitudinal section of the lock along a line B-B. Figure 5 is a longitudinal section of they lock alongvline C-C inFigure 2. Figure 6 is a modification of said lock. Figure 7 is a view of the Y Specification of Letters Patent.

bolt. Figure 8 is an edge view thereof. Figure shows the device for actuating the carrier. Figure 10 shows the carrier. Figure 11 is a. view of its edge L -b. Figure 12 is a view of its edge a-c.

The lock embodied in my invention comprises a metal casing 1` and a keeper 2, with which it is arranged to lock, and subsequently to the locking operation, tc interlock said casing with said keeper. The object is accomplished by means of a bolt 3 having one or more hooks or interlocking bolts, il, on the outer or locking end thereof.

said bolt being ixedly attached to a. frame 5 which is slidably mounted in the lock casing and is adapted for moving said bolt into andV out of locking position, and subsequently to the locking operation, to move said bolt into and out of engaging or interlocking position. rlhe keeper 2 is provided with horizontal or locking chambers for receiving the bolts in locking position and vertical recesses `for the hooks or interlocking bolts; said recesses are preferably formed by crosspieces 38 and 37, the latter being so positioned in the keeper as to allow the main bolt in addition to the hooks to enter the keeper and thereby more properly secure ythe door.

A carrier 8 is provided with an arm 9, and preferably a groove 36 for guiding its movement in the casing. The carrier isprovided. with studs 10, 1l and 12. The frame 5 of bolt 3 embraces slots or grooves 6 and which are respectively adapted to receive said studs 'l1 and 10, and which cooperate to gui-de the movement of the bolt into and out of locking position, and subsequently to the locking operation said studs 10 and 1l are adapted to move said bolt into engaging or interlocking position kthrough the mechanism for actuating said carrier 8.

The device for actuating the carrier com!` prises a frame 50 adapted for slidable move- VIO slots to move the bolt into engagement with the keeper subsequently to the locking operation.

A pawl 14 is pivoted on bolt traine 5 at 21 and embraces a pivot head 20, a'spring 2:2 and a stop pin 23; a projection 19 bearing on the projection 18 of frame 5, and a ledge 15 abutting on a. lug 16 on said casing 1. Another pavvl 30 is pivoted on frame 50 at 33, and is provided with a, pivot head 32, a projection 31 bearing aga-inst projection 26, a ledge 29 abutting on a lug 28 on the casing 1, and a spring 34 leaning` stud 35. The frame p-rovided with another projection 17, and iframe 50 has another` projection 2"?. -rn arm or cam- 25 is mounted upon a rotatable sleeve 24 Whiclris arrai'iged to be operated' by key or knob mechanism to successively move said bolt into locking and interlocking position and in the reverse movement from the interlocking to locking position and back to unlocking` position.

The modified type shown in Figure 6 differs 'from the preferred type shown in Figure 1, in that the carrier 8 is not provided with an arm 9 and embraces only tivo studs 10 and 12; said stud 10 beingreceived in slot 7 on the bolt frame 5, stud 12 being taken into cam slot 13 of frame 50, and as in the invention tiled January 2nd,`a stud 11 on the casing is arranged to be received into slot G on the bolt frame. as a guide in conjunction with stud 10 on the carrier during the movement oi the bolt into and out of locking position, said stud 11 acting as a pivotal point during the movement of the bolt into engagingposition with said stud 10 as the actuating means. In other Words, the cam in my invention of January. 2nd is replaced by a carrier 8 for moving the bolt into engaging position upon stud 11 as a pivot.

The operation is as follows:

In performing the locking operation, cam 25 first bears against projection 19 of paivl 14 and releases the boltl frame 5, and then bears against projection 18 of said frame 5 and moves bolt 3 into locking position. in the keeper 2 said studs 10 and 11 on the carrier acting as guides. As. the cam 25 continues to revolve in the direction of arrow 61 subsequently to having performed the locking operation, it bears against projection 3 1 of paivl 30 and releases trame 50; it then bears against projection 2G oi' said frame 50 causing it to move in a direction away. from the keeper, and in the progress ot said movement causesstud 12 to cooperate with cam slot .13 in said 'trame 50 to force said carrier in a direction to move the bolt 3 into engaging' position ivithhooks or interlocking bolts 4 delivered into the interlocking chambers 4 in keeper 2Q Zhen the bolt 3 is moved into locking position bythe inagainst a This stud 11 acts,

strumentality of said key or knob mechanism pawl 14 maintains it in such position and prevents the reverse movement of the bolt. PaWl 30 is arranged to prevent the return of the carrier 8 to inoperative position and thereby the return ot the bolt from engaginff position to locking position.

IBy the reverse movement of thel key or knob mechanism, the bolt 3 is first returned from its interlocking position to locking position and then from locking to inoperative position.
